What is MacKeeper Helper and what does it do?

MacKeeper Helper is a component of the MacKeeper software suite, which is designed to optimize and secure macOS systems. The function of MacKeeper Helper revolves around improving the efficiency of the main MacKeeper application by managing background tasks, such as cleaning up junk files, performing virus scans, and optimizing system performance. It is intended to run discreetly in the background, aiding in the smooth operation of the suite's various tools without requiring direct user intervention. Critics have raised concerns about MacKeeper's marketing tactics and usefulness, but MacKeeper Helper itself serves as a dedicated process to facilitate the execution of MacKeeper's feature set.
